In this paper, we propose an optimization method for the broadcast rate in\nvehicle-to-vehicle (V2V) broadcast communications at an intersection on the\nbasis of theoretical analysis. We consider a model in which locations of\nvehicles are modeled separately as queuing and running segments and derive key\nperformance metrics of V2V broadcast communications via a stochastic geometry\napproach. Since these theoretical expressions are mathematically intractable,\nwe developed closed-form approximate formulae for them. Using them, we optimize\nthe broadcast rate such that the mean number of successful receivers per unit\ntime is maximized. Because of the closed form approximation, the optimal rate\ncan be used as a guideline for a real-time control-method, which is not\nachieved through time-consuming simulations. We evaluated our method through\nnumerical examples and demonstrated the effectiveness of our method.\n
